Scholar’s Advanced Technological System

After coming out of the Nanjing Institute of Advanced Studies, Liu Academician felt that the whole person was like a sleepwalker, and his head was in chaos.

After the physical demonstration, Lu Zhou followed the theoretical level to the experts from the Chinese Academy of Sciences to explain the application of topological quantum theory in the model insulator and how he integrated through some basic carbon-based Circuit components and Josephson knots to achieve the Mayorana Fermi son.

Objectively speaking, it is somewhat difficult to understand the complex physics mathematics formulas that you want to understand.

Fortunately, although the formula accounts for more than 70%, there are dynamic graphics as a demonstration, so that they are not completely unable to understand the found mystery.

It was only after listening to this “Don’t Make a Difference” class, he felt that he had spent decades establishing the World view, and almost the whole was refreshed.

It takes less than 1024 seconds to disassemble the product of prime numbers above the 1 bit, which at least shows the calculator in his hand, with qubits at least above 500.

However, this is not the most critical. The most important thing is that this quantum computer is only the size of a palm! The size of the quantum computer in the Chinese Academy of Sciences is not known how many times smaller!

And if they are horizontally contrasted, they do the best, only 20 qubits…

This is the latest result of this year.

In addition, compared to the quantum computer of the size of the box, what shocked him was the academician who stood on the stage and explained the theory to them.

Mathematics, physics, materials, and integrated circuit design… If you take a closer look, the knowledge points covered in this lesson can even subdivide more than a dozen subject branches.

However, for the young people who are less than 30 years old, the esoteric and awkward knowledge is in his hands like a hand, and there is no obstacle in its use.

If he didn’t see it with his own eyes, he couldn’t believe it. Someone on this world can be excellent to this extent.

Perhaps this is why he can overcome one World after another problem…

Sitting on the car parked at the entrance of the institute, Liu Academician suddenly sighed with emotion.

“I feel… maybe I need to go back to school and re-learn.”

Director Li’s expression is still calm.

After all, the surprise was a surprise. It was only for the technology itself. As for the esoteric theories, he couldn’t understand it anyway, so he didn’t go to the heart.

Looking at the sly Liu Academician, he said comfortably.

“…after all is a fellow academician, his class is really difficult to understand, and you should not go too far. I believe that you don’t understand it, even if other people come here to sit.”

“It’s not a question that goes to my heart,” Liu said, shaking his head and saying, “It’s just that sometimes I really feel that I have been unable to keep up with this era.”

“The topic of topological quantum computing is relatively new, but there are people in our field who are doing it. The target is Microsoft’s Mayorana Fermi son’s project. However, whether it is the project of Pan Academician, or the one in our company. The project against Microsoft, or Microsoft’s own… Qubit is always just above the 20th and 30th.”

Upon hearing this, Secretary Li did not care for him, and asked quickly.

“How many of the Luss Professionals have done?”

Academician Liu: “I forgot to ask how much, but as far as the show is concerned… at least 500 is there.”

500…

This is an order of magnitude higher!

The car was silent for a long time.

After a short while, Director Li came back to his senses and sighed.

“…is really scary.”

……

If the importance of technology itself is the importance of quantum technology, it is no doubt that it is far more than the carbon-based microchip itself.

It is even exaggerated to say that even the controllable fusion technology can be placed together with the terms of equality terms.

According to the accepted view, the three pillars of modern technology are energy, information, and materials, and quantum computers have basically stood at the apex of this century’s imaginary and hopeful realization of information technology in the future.

And not just that.

The most important thing is that the traditional encryption method is like being stripped out in front of the quantum computer, and it is completely undefended.

This is also the most terrifying place for this technology.

As we all know, not only IT and finance, the security of modern information networks 90% relies on asymmetric public key encryption, and the most widely used is RSA encryption algorithm.

Since the factorization of large prime products has no fixed formula and only a unique solution, in principle, as long as the product of the prime numbers used is large enough, then it is basically equal to no solution, even if it is not the Pro Professor. It may be calculated in the lifetime.

However, in the face of quantum computers, this problem that requires hundreds of years to solve for traditional computers can be solved in a matter of seconds or even seconds.

Even if one might say that the asymmetric public key encryption algorithm is not just RSA, there are elliptic curve encryption, Elgamal encryption, etc. based on discrete logarithm…

But what is it in the face of the computing power of quantum computers?

I am afraid I can’t even talk about the trouble.

After returning home at night, Lu Zhou, sitting at the desk, thought for a long time, and finally took out a stationery and wrote it on it with a pen.

【

… The changes brought about by quantum computers in the field of communication technology will be subversive.

The encryption and decryption methods of communication technology have always been in a state of dynamic balance. However, the breakthrough of topological quantum computing technology has already broken the balance between this offensive and defensive.

Decrypting a traditional asymmetric public key encryption problem takes only a few seconds.

Once this technology is popularized, it will bring huge security risks to our society.

The immediate priority is that we must establish a more rigorous and more reliable encryption algorithm as a replacement for the original encryption method.

A quantum cryptographic algorithm similar to the bb84 protocol is a good choice, but a quantum computer with a quantum bit above 1000 will still be powerless.

The quantum computer technology of qubits above 1000, in my opinion, can be broken through in a short time.

Therefore, this new encryption rule must be more reliable than the bb48 protocol, or even an improved version of BBM92.

Once you master this new encryption technology, it is the best time to promote the commercialization of quantum computers.

And by that time, we will have the information technology advantages that other countries cannot match.

Just like the controllable fusion technology, the advantages we have built for us in the energy field.

Stopping the pen, Lu Zhou found an envelope from the drawer, stuffed the letter in, and threw it at the corner of the table.

When he goes to National Quemoy University tomorrow, he will throw it to Wang Peng and ask him to find someone to go to Chang’an Street in Beijing.

Although he feels that he does not say anything, Director Li will certainly report to it, but on this issue, sometimes the opinions of experts will be more useful, and it will be more likely to attract the attention of the top.

Although these things are not a matter that Scholar needs to worry about, if you can, Lu Zhou still hopes that his research will bring some positive impact to this world, rather than pushing it in a bad direction.

Although this may not be as exciting as the scientific research itself.

But it is also part of the fun.
